How to Make a HeyGen-Style Video on HeyOz

Spokesperson video without the studio, the teleprompter, or the retakes.

START THE HEYGEN WORKFLOW
STEP 1

START THE HEYGEN WORKFLOW

Open the Content Studio and pick the avatar or spokesperson workflow. HeyOz routes it to Seedance 2.5. Upload what you want held steady: photos or a short clip of the person, a voice reference, your product, and any style boards. Up to fifty assets can go in.

WRITE THE SCRIPT AND THE SCENE
STEP 2

WRITE THE SCRIPT AND THE SCENE

Write the spoken lines, then the setting, the framing, and how the delivery should feel. Because sound is generated with the picture, the line you write is the line that gets performed and lip synced. Lay the beats out in order and the model follows the sequence.

SET FORMAT AND GENERATE
STEP 3

SET FORMAT AND GENERATE

Choose your duration up to thirty seconds, your aspect ratio, and 480p or 720p. Click Create. If one moment lands wrong, edit that timestamp rather than rerolling the whole thing, and extend the clip in another round if you need more runtime.

Why HeyGen Work Runs on Seedance 2.5 Here

HeyGen built the avatar category. The generation models have since caught up and moved past it for ad and UGC work, so that is what we point you at.

THE SWAP, EXPLAINED

HeyGen Requests Are Served by Seedance 2.5

Ask HeyOz for a HeyGen-style video and Seedance 2.5 handles it. The reason is scope. An avatar tool animates a face over a script. Seedance 2.5 generates the whole shot, the person, the setting, the camera move, and the sound, in one pass, and lets you edit any part of it afterwards. For ads and social video that is a different class of output, not a cheaper substitute.

ONE TAKE, THIRTY SECONDS

A Full Thirty Seconds in a Single Pass

Seedance 2.5 generates up to thirty seconds of audio and video in one generation, and supports multiple rounds of extension after that. That is long enough for a complete spot with a hook, a demo, and a call to action, held together as one continuous piece of work instead of assembled from short clips that never quite match.

SPEECH IN THE SAME TAKE

Dialogue, Lip Sync, and Sound Together

Picture and audio are decided together inside the same generation, so a footstep and the frame the foot lands in agree with each other. That covers dialogue with accurate lip sync across languages, along with music, effects, and room tone. No separate voice step, no re-syncing a track to a mouth that was animated without it.

FIFTY REFERENCES

Lock the Face, the Set, and the Palette

You can hand Seedance 2.5 up to fifty multimodal references in one generation: photos of a person, clips, audio, product shots, and style boards. It holds the character, the location, and the colour palette across the full take. Timestamp-level editing then lets you fix one moment in the clip without regenerating the parts that already worked.

Built for Every Kind of Avatar Video

Everything you came to HeyGen for, plus the scene around it.

Spokesperson and UGC Ads

A person to camera holding your product, talking like a customer rather than a corporate video. Because the model generates the room, the lighting, and the handheld feel along with the person, you get something that looks filmed on a phone in a real kitchen instead of a floating head on a background plate.

Character-Led Content

Pick a face for your brand and reuse it. Reference images hold the identity across scripts, settings, and outfits, and the voice reference keeps them sounding the same too. Run twenty ads and it reads as one recurring presenter, which is the whole point of an avatar in the first place.

Multilingual Versions

Selling in more than one market means the same script in more than one language. Seedance 2.5 handles dialogue with accurate lip sync across languages, so a Spanish or Urdu version is generated properly rather than dubbed over a mouth that is speaking English. Write the line in the language you need and the mouth matches.

Social Clips With Sound

Feeds move fast and silent video gets skipped. Every generation comes back with finished audio already cut to the picture, sized for vertical. Thirty seconds is a full TikTok or Reel, so your clip lands ready to post rather than needing a voiceover pass and an edit first.

FAQs

Why does HeyOz route HeyGen requests to Seedance 2.5?

Because for ad and social work the general video models have overtaken dedicated avatar tools. Seedance 2.5 gives you thirty seconds in one pass, native audio with lip sync, up to fifty references, and timestamp editing, and it generates the whole scene rather than animating a face over a static background. You get the spokesperson video you came for, with the ad around it.

What is Seedance 2.5?

Seedance 2.5 is ByteDance's current video model, released at the end of July 2026, and it generates picture and sound jointly in a single architecture. It runs text to video, image to video, and reference to video, takes up to fifty multimodal references, produces up to thirty seconds per generation with multi-round extensions, and supports timestamp-level editing of both audio and video.

Is there anything HeyGen still does better?

Yes, and it is worth being straight about it. HeyGen is purpose-built for long-form talking-head video, real-time interactive avatars, and dubbing an existing recording into a long list of languages, and it does that at lengths no generation model matches. If your job is a thirty-minute training module or a live avatar agent, that is HeyGen's territory. For short ads, UGC, and social video, Seedance 2.5 is the better tool.

What resolution and duration does it export?

Seedance 2.5 generates at 480p or 720p, up to thirty seconds in a single pass, with further rounds of extension available if you need more length. Audio comes back with the clip, and you can edit a specific timestamp rather than regenerating the whole take.
